ANAHEIM, Calif. – September 20, 2017 – DataON, an industry-leading provider of hyper-converged cluster appliances (HCCA) and optimized storage systems for Windows Server environments, today announces the first commercially available Kepler-47 hyper-converged infrastructure for Windows Server 2016 Storage Spaces Direct:

“DataON is exclusively focused on customers who have the ‘Microsoft choice’ for their software-defined data centers,” said Howard Lo, vice president of sales and marketing, DataON. “We were intrigued by the Project Kepler-47 proof-of-concept last year and we wanted to accept the challenge to bring the first Kepler-47 appliance to market. We are excited to introduce the Kepler-47 appliance, a budget-friendly Storage Spaces Direct two-node solution for customers with small and ROBO deployments. We are proud to work with Microsoft, Intel, and MSI to make this concept a reality.”

Claus Joergensen, Principal Program Manager for Storage Spaces Direct, Microsoft Corp. said, “Project Kepler-47 was a proof-of-concept that was born during our development of Storage Spaces Direct over the past 4 years. The question that we were trying to answer for our customers was ‘how low can you go?’ We had a high-performing, resource-efficient and budget-friendly product in Storage Spaces Direct and we wanted to see if it was possible to create a low-cost appliance that could run Storage Spaces Direct to meet the needs of small and ROBO deployments.”

Kepler-47 uses Intel Thunderbolt 3 over a USB Type-C connector instead of traditional Ethernet networking between the servers. This eliminates the need for costly high-speed network adapters and switches. Thunderbolt 3 provides up to 40Gbps throughput, plenty for replicating storage and live migration of virtual machines.

“This is a new and exciting application for Thunderbolt technology”, said Jason Ziller, General Manager, Client Connectivity Division at Intel. “The ability for Thunderbolt 3 to provide low-cost 10GbE networking makes it a perfect complement for Storage Spaces Direct to provide a low-cost hyper-converged infrastructure.”

DataON partnered with MSI to design the Kepler-47 appliance, including the chassis, motherboard and components.

“DataON and MSI have been long-time partners in creating hyper-converged cluster appliances,” said Norman Tsai, General Manager of Enterprise Platform Solutions BU, MSI. “When DataON approached us about the Kepler-47 concept, we were enthusiastic to support this project and provided our rich x86 platform design and production resources.”

The Kepler-47 appliances will be featured at the DataON booth (#1726) at Microsoft Ignite 2017, from September 25-29, 2017 in Orlando, Florida.


DataON Kepler-47 solutions are built to optimize the full stack of Microsoft Storage Spaces Direct in a hyper-converged platform. They are designed with integrated compute, network and storage infrastructure with near-linear scalability to simplify and maximize the deployment of Microsoft applications, virtualization, data protection and hybrid cloud services. These pre-configured 2-node clusters are capable of supporting up to 20 Hyper-V VMs per nodes, for expanded capacity and operational flexibility.

DataON Kepler-47 solutions deliver:

  • Simple 2-node hyper-converged infrastructure – Provides high availability and storage for enterprise applications with over 10TB usable capacity in a mirrored configuration.
  • Hyper-V virtualization – Supports more than 20 Hyper-V virtual machines per HCI deployment.

Low-cost, high-speed networking –Thunderbolt 3 provides simple, standardized and cost effective connection with the highest appliance I/O bandwidth, eliminating the need for costly network adapters and switches in many implementations.

Small Form Factor – Saves space with a footprint more than 50% smaller than a standard 2U rack server.

  • High Availability and Resiliency – The servers form one Windows Server 2016 failover cluster with Cloud Witness as low-cost, low footprint quorum technology.
  • Fault Tolerant – Uses local drives and leverages Storage Replica with Azure Site Recovery.

Integrated data protection and guarded fabric – Supports Windows Server 2016 with Shielded VM and TPM 2.0 trusted attestation for security and business continuity.



All DataON Kepler-47 solutions are pre-configured with DataON MUST (Management Utility Software Tool) infrastructure visibility, monitoring and management software. Fully integrated with the Windows Storage Health Service API (SM-API), it provides advanced cluster monitoring, performance metrics, system health statistics, and automated system alerts for Windows Server 2016 Storage Spaces Direct.

MUST delivers SAN-like storage monitoring features through a single pane of glass, providing real-time dashboard level metrics for IOPS, latency, and throughput on cluster nodes and volumes. With system alerts based on Windows Health Service faults and SAN-like call home services, systems administrators can be automatically notified of hardware failures, configuration issues and resource saturation.

DataON is the first to market with a tool that provides visibility, monitoring and management of your Windows Server 2016 deployments.
